Having a function change the value a pointer represents in C

Question

I have a main function that has a char, I am attempting to pass a pointer to that char into a function and have it change it from A to

Answer 1

You want to change the value the pointer points to, not the pointer itself.

Thus you need to dereference the pointer with *pointer:

void setChar(char* charToChange) {
    *charToChange = 'B';
}

If you don't, you just change the local value of charToChange.
